Description
Ethyl propiolate is an activated alkyne ester supplied at min. 95 % purity, with CAS number 623-47-2 and empirical formula C₅H₆O₂. The compound has a molar mass of 98,1 g/mol, a density of 0,968 g/cm³, a flash point of 25 °C and a boiling point of 119 °C. These properties make it a versatile reagent for cycloadditions, conjugate additions and the construction of heterocyclic frameworks in organic synthesis. This grade from manufacturer Carl ROTH is well suited to click-chemistry approaches, propiolate-based coupling strategies and the synthesis of functionalised acrylic derivatives. Clear physical constants aid safe handling and process planning under standard laboratory conditions. Researchers in medicinal chemistry, materials science and fine-chemical development can rely on the stated CAS identity and molar mass for reproducible experimental design. The product is intended for professional laboratory use within the chemicals and biochemicals portfolio.

Questions about Ethyl propiolate, min. 95 %, 100 g
What is this article?
Ethyl propiolate, min. 95 %, 100 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
